Dynamic survivable RWA strategy on IP over WDM networks

To provide the robust message delivery capability with traffic flows in the networks, survivability become a key issue for the service provider to guarantee the service level agreement to the customers. In this paper, we propose the group-based routing and wavelength assignment policy for dynamic traffic demands under WDM optical networks on IP/GMPLS/WDM environment. We consider the survivable routing and wavelength assignment strategy for dynamic traffic demands under static partitioned network. The extensive simulation results show the efficiency of the proposed protection approach.
